What Is Sky Protocol (USDS)? MakerDAO Rebrand Complete Guide 2026

What Is Sky Protocol (USDS)? The MakerDAO Rebrand Explained in 2026

MakerDAO was the first protocol to prove that an algorithmic, collateral backed stablecoin issued entirely on chain could survive a full market cycle without depegging into oblivion. From the launch of single collateral DAI in 2017 to the multi collateral system that powered DeFi summer in 2020, Maker became the quiet plumbing under almost every yield strategy that needed dollar denominated leverage. Then in 2024 the project did something almost unprecedented in DeFi: it rebranded. The Maker brand, the DAI token, and the MKR governance token did not disappear, but they were joined by a parallel system called Sky Protocol with its own stablecoin USDS and its own governance token SKY. By 2026, Sky has become the primary brand and the front door for new users, while the legacy Maker rails continue to operate underneath.

Sky Protocol is the rebranded, restructured continuation of MakerDAO, designed around the multi billion dollar Endgame plan written by founder Rune Christensen. Endgame is a multi year roadmap that splits the monolithic Maker into a network of SubDAOs, introduces a freezable variant of the stablecoin (USDS) alongside the unfrozen DAI, replaces the MKR governance token with SKY at a 1 to 24,000 ratio for those who choose to upgrade, and ships features like the Sky Savings Rate that pays USDS holders a programmable yield set by governance. The architecture is more ambitious and more complicated than the old Maker stack, but the goal is the same: keep a fully decentralized dollar stable, scalable, and useful as a settlement layer for the rest of DeFi.

This guide walks through what Sky Protocol actually is, why MakerDAO rebranded, how USDS differs from DAI, how the SKY token relates to MKR, how the Sky Savings Rate works in practice, and how Sky compares head to head against the other major decentralized stablecoin issuers in 2026. By the end you will understand the protocol well enough to decide whether USDS belongs in your portfolio and whether the upgrade from MKR to SKY makes sense for your situation.

From MakerDAO to Sky, the Rebrand in Plain English

To understand Sky you have to understand why MakerDAO decided to rebrand at all. By 2023 the protocol was the largest decentralized stablecoin issuer in the world, with DAI used across virtually every chain and integrated into nearly every yield strategy. But Maker had a problem that grew larger every year: it depended heavily on real world asset collateral, particularly short term US Treasury bills, which generated most of the protocol's revenue but also made DAI uncomfortably correlated to a single jurisdiction and a single asset class. Worse, USDC backing inside Peg Stability Modules tied DAI's stability to a centralized issuer that could freeze tokens at any time. The protocol was decentralized in name but had real centralization vectors hidden in its collateral mix.

Rune Christensen, Maker's founder, responded with the Endgame plan, a sprawling document that proposed splitting the protocol into a constellation of SubDAOs, introducing a new dollar token that could be optionally freezable to satisfy regulators, expanding into prediction markets and AI assisted governance, and rebranding the whole stack under a new name. The community ratified the plan over several years of governance votes, and in August 2024 the new brand went live. Sky Protocol launched with USDS and SKY as the new flagships, while DAI and MKR continued to function in parallel for users who preferred not to upgrade. The dual track design lets long term Maker holders keep using the old tokens forever if they want, while new users default into the Sky tokens with their additional features.

The practical effect for most DeFi users in 2026 is that the front end at sky.money has replaced the old oasis.app interface, the term Sky has replaced MakerDAO in most discussions, and USDS has become the default stablecoin issued by the system. The technical core is mostly the same. The same vaults mint the same kind of collateralized stablecoin. The same governance process decides on collateral types and risk parameters. But the surface has been redesigned, the token economy has been compressed by the 1 to 24,000 split, and a freezability switch sits inside USDS waiting to be activated by governance if regulators ever demand it. For an overview of how decentralized stablecoins fit into the broader landscape, the DeFi primer covering AMMs, lending markets, and stablecoins is the right starting point.

Rune Christensen and the Origins of MakerDAO

MakerDAO was founded by Rune Christensen, a Danish entrepreneur who started writing about a decentralized dollar token as early as 2014. The original whitepaper sketched a system in which any user could lock ether as collateral and mint a dollar pegged token against it, with the system maintaining the peg through a combination of overcollateralization, on chain liquidations, and a governance token that absorbed risk and earned protocol fees. The first version, single collateral DAI launched in December 2017 on Ethereum, accepted only ETH as collateral and used a stability fee paid in MKR to incentivize good debt management.

Multi collateral DAI launched in November 2019 and was the breakthrough that turned Maker into the foundation of DeFi. By accepting any approved ERC20 as collateral, the system could support wrapped Bitcoin, stablecoins, LP tokens, real world asset vaults, and dozens of other types of backing. DAI scaled from sub one hundred million in supply to over five billion at peak, with TVL inside Maker vaults touching twenty billion dollars during the 2021 bull market. The protocol survived black Thursday in March 2020, when a price oracle outage triggered cascading liquidations and required an MKR debt auction to cover bad debt. It also survived multiple regulatory pressure waves, including the 2023 USDC depeg that briefly knocked DAI off its peg because of USDC backing in the Peg Stability Module.

Timeline: From Maker to Endgame to Sky

USDS, the New Sky Stablecoin Explained

USDS is the dollar pegged stablecoin issued by Sky Protocol. Like DAI before it, USDS is minted when users open collateralized debt positions inside Sky vaults, depositing approved collateral types like ETH, wstETH, wBTC, and various stablecoins and tokenized real world asset positions, then drawing USDS against that collateral up to a maximum loan to value ratio set per vault. The system maintains the peg through a combination of overcollateralization, on chain liquidations when positions become unhealthy, the Peg Stability Module that allows direct 1 to 1 swaps between USDS and other major stablecoins, and stability fees that the protocol earns and can use to defend the peg.

The single most important difference between USDS and DAI is the inclusion of a freezability switch in the USDS contract. Sky governance can vote to freeze specific USDS balances if required to comply with sanctions or law enforcement actions, while DAI remains permanently unfreezable. This is a deliberate, controversial design choice meant to give regulators a relief valve so that they do not pressure the entire protocol over a single illicit address. The freezability has never been activated as of mid 2026, and governance has signaled that activation would require an extraordinarily high threshold of votes, but the optionality is built into the code and is a defining philosophical difference between the two tokens. Users who want maximum censorship resistance can stay in DAI. Users who prefer the additional features and active development effort going into the Sky brand default to USDS. For background on how stablecoins fit into the broader landscape, the stablecoin primer covering algorithmic, collateralized, and fiat backed designs walks through the trade offs.

Beyond the freezability switch, USDS works almost identically to DAI from a user perspective. The peg holds within tight bands around one dollar in normal market conditions. The token trades on every major DEX and is supported by CEXes including Coinbase, Binance, and Kraken. The supply grows when borrowers open vaults and shrinks when they repay, and the protocol earns stability fees on every outstanding USDS that flow into the Sky Savings Rate, the surplus buffer, and the SKY buyback and burn mechanism. By mid 2026 USDS supply has grown from zero at launch to over six billion, while DAI supply has fallen modestly as users migrate to the new token.

The SKY Token and the MKR to SKY Conversion

SKY is the new governance token of Sky Protocol, launched alongside USDS in August 2024. The total supply is set at 24 billion SKY, a number that is exactly 24,000 times the legacy MKR supply of one million tokens. The reason for this specific multiple is that any MKR holder can upgrade their MKR to SKY at a fixed 1 to 24,000 ratio at any time using the official upgrade contract. The conversion is optional and reversible. MKR holders can stay in MKR and continue using the old governance interfaces if they prefer, while those who upgrade get access to Sky specific features like the Sky Savings Rate boost, governance voting on Sky proposals, and the SKY only farming rewards distributed by the protocol.

The rationale for the token split is mostly cosmetic and practical. MKR traded at multi thousand dollar prices through most of its history, which made the token feel inaccessible for small users and clumsy for governance proposals that wanted to denominate rewards in whole tokens. By splitting MKR into 24,000 SKY, the protocol gave the new token a more familiar price point in the low single digits or single cents range. The economic value of holding the two is identical when you account for the conversion ratio, so the split does not dilute anyone and does not change the protocol's fundamentals. What it does change is the user experience for farming, voting, and quoting prices.

SKY holders have three primary economic exposures. First, they receive a share of protocol revenue through buybacks. The protocol uses stability fees and excess reserves to buy SKY on the open market and burn it, reducing supply and creating a deflationary pressure for active holders. Second, they vote on governance proposals that decide collateral types, risk parameters, savings rate, and SubDAO funding. Third, they absorb protocol risk through the SKY backstop. If the protocol ever becomes undercollateralized due to a black swan liquidation failure, SKY would be minted and sold to cover the shortfall, diluting existing holders. This is the same role MKR played and is the reason SKY holders have skin in the game even when they are not directly using the protocol.

The Sky Savings Rate and How It Pays

The Sky Savings Rate, abbreviated SSR, is the variable yield that the protocol pays to holders of USDS who deposit their tokens into the SSR contract. The mechanism is conceptually simple. The protocol earns revenue from stability fees on borrowers, from yield on real world asset collateral, and from peg stability module spreads. A portion of that revenue is distributed to SSR depositors as additional USDS, increasing their balance over time. The current rate is set by governance through SKY votes and can range from zero to whatever level the protocol's revenue allows, though in practice it tends to track the broader rate environment with some lag.

In mid 2026 the SSR sits around 6 percent annualized, slightly above the comparable rate offered by the legacy DAI Savings Rate. The premium reflects two factors. First, governance has explicitly favored migration to USDS by paying SSR holders a bonus relative to DSR holders, which incentivizes the migration the protocol wants. Second, USDS holders benefit from additional revenue streams that DAI holders do not, including SKY farming rewards on certain DEX integrations. The combination has been effective: USDS supply has grown faster than DAI supply has shrunk, and the share of total Sky stablecoin supply in USDS has crossed 60 percent.

Using the SSR is straightforward. Connect a wallet to sky.money, deposit USDS into the savings module, and your balance accumulates yield in real time. Withdrawals are instant and have no lockup. There are no fees on deposit or withdrawal. The only consideration is that yield is paid in USDS, so your principal currency is dollar denominated and your return is dollar denominated. For users who want exposure to a stable yield without depending on a centralized issuer, SSR has become one of the most popular destinations in DeFi. The crypto staking guide covers how yields like SSR compare to validator staking and other yield products.

SubDAOs and the Endgame Structure

A core component of the Endgame plan is the gradual decomposition of the monolithic Maker into a constellation of SubDAOs called Stars. Each Star is a semi independent organization with its own focus, its own token, its own governance, and its own treasury, while remaining connected to the main Sky governance through a defined set of protocol level constraints. The original Endgame document envisioned six Stars at launch, each handling a different vertical: RWA collateral, native crypto collateral, growth, decentralized AI, prediction markets, and ecosystem development.

By 2026 the Star system has launched the first wave with Spark Protocol as the lending Star, Endgame Ventures as the growth Star, and a handful of smaller experimental SubDAOs in early stages. Spark is the most visible and operates a Compound style lending market that is tightly integrated with USDS, offering some of the deepest USDS lending and borrowing liquidity in DeFi. Each Star issues its own token that holders of SKY can farm by locking into the staking module, creating a flywheel where SKY exposure also generates exposure to the broader Sky ecosystem.

The Star structure is the most ambitious part of Endgame and also the most controversial. Supporters argue that it lets Sky scale into many different verticals without making the main protocol bloated and ungovernable. Critics argue that it dilutes attention, creates governance complexity, and risks fragmenting liquidity across too many semi independent tokens. The verdict is still open, but the early signs from Spark have been positive enough that the second wave of Stars is scheduled to launch through 2026 and 2027.

Key Features of Sky Protocol

Sky inherits the full feature set of late stage MakerDAO and adds several new capabilities that are unique to the rebrand. The collateralized debt position system remains the core, letting users deposit ETH, wstETH, wBTC, and other approved tokens to mint USDS against them. The Peg Stability Module continues to allow direct stablecoin to stablecoin swaps at 1 to 1 with a small fee, providing the most important peg defense mechanism. The liquidation system runs Dutch auctions to wind down unhealthy positions automatically without protocol intervention.

New under the Sky brand are the Sky Savings Rate as described above, the Sky Token Rewards program that pays SKY to USDS holders who lock into specific savings tiers, the Smart Burn Engine that converts protocol surplus into SKY buybacks and burns the bought tokens, and the unified front end at sky.money that surfaces all these features in a single interface rather than spreading them across multiple legacy domains. Real world asset collateral continues to grow as a share of total backing, with tokenized US Treasury vaults from issuers like Monetalis and BlockTower contributing the bulk of yield revenue.

Use Cases for USDS in DeFi

USDS is used across DeFi in essentially every role a stablecoin can play. The most common is as a swap pair on DEXes, where USDS is paired against ETH, BTC, and other major assets on Uniswap, Curve, and Balancer, providing a settlement currency for traders who do not want exposure to a centralized stablecoin issuer. The second is as a savings vehicle, with users depositing USDS into the SSR or into lending markets like Spark and Aave to earn yield. The third is as collateral, since USDS is accepted as collateral by most major lending protocols and DEX aggregators that need a stable margin asset.

For traders who want leverage, USDS borrowed against ETH or wstETH vaults is one of the cleanest ways to express a leveraged long ETH position without depending on a centralized lender. For yield farmers, the combination of SSR plus SKY token rewards creates a stable, dollar denominated yield that often outpaces what is available from staking treasuries directly. For DAOs and treasuries, USDS offers a decentralized alternative to holding USDC or USDT, with the trade off that the freezability switch exists even if it has never been activated. The DeFi lending and borrowing guide covers how stablecoins like USDS fit into broader credit strategies.

Sky vs Frax vs Liquity vs Crvusd

The decentralized stablecoin space in 2026 has consolidated around four serious players: Sky with USDS and DAI, Frax with FRAX and frxUSD, Liquity with LUSD and BOLD, and Curve with crvUSD. Each has a distinct design philosophy and trade off profile, and understanding the differences is the best way to decide which stablecoin belongs in your portfolio.

Sky is the most established, the most liquid, and has the most extensive collateral mix including significant real world asset exposure. The trade off is that this RWA exposure introduces centralization vectors and the freezability switch on USDS gives governance a censorship lever, even if it has never been used. Frax has evolved through several designs and now relies primarily on tokenized treasuries to back frxUSD, similar to USDS but with a more aggressive yield optimization layer through Fraxlend and the frxETH liquid staking product. Liquity is the purest decentralized stablecoin, accepting only ETH and a few liquid staking tokens as collateral and explicitly refusing to add RWAs, with its V2 release adding the BOLD stablecoin that introduces user set interest rates. Curve's crvUSD uses the LLAMMA soft liquidation mechanism that makes liquidation less painful but requires users to manage health factors carefully.

For users who want maximum decentralization, Liquity is the strictest choice. For users who want maximum liquidity and DeFi integration, USDS is the default. For users who want yield optimization layered on top of a stablecoin, frxUSD and the Frax ecosystem are interesting. For users who already hold significant collateral on Curve and want minimal liquidation pain, crvUSD is worth a look.

Sky Roadmap and What Comes Next in 2026

The 2026 roadmap for Sky Protocol centers on three priorities. First, completing the migration from DAI and MKR to USDS and SKY by continuing to offer attractive savings rates and farming incentives on the new tokens. The goal is to push USDS supply past ten billion and SKY market cap into the top tier of DeFi governance tokens. Second, launching the next wave of SubDAO Stars, with Endgame Ventures expanding its growth investments and at least two new Stars targeting decentralized AI and prediction markets respectively. Third, scaling real world asset collateral while maintaining careful counterparty diversification, with the goal of generating sustainable yield that does not require dependence on any single jurisdiction.

Longer term, the Endgame plan envisions a multi chain deployment where Sky operates natively on multiple L1s and L2s rather than only on Ethereum. The protocol has been cautious about cross chain expansion to avoid bridge risk, but the 2026 roadmap includes initial deployments on Base and Optimism with USDS bridged through the canonical Maker Teleport infrastructure, which is more conservative than third party bridges. By 2027 the protocol expects to be deployed across at least four major chains and to be running at least six active Stars, with USDS supply targeting 25 billion and SKY buybacks compounding at over a billion dollars per year.

How to Buy USDS and SKY, and Where to Use Them

Acquiring USDS is straightforward. Centralized exchanges including Coinbase, Binance, Kraken, and OKX list USDS for direct purchase against USD or USDC. On chain, USDS trades on every major DEX with the deepest pools on Curve, Uniswap, and the Sky native Peg Stability Module. The PSM is the cleanest way to convert large amounts of USDC into USDS at a 1 to 1 ratio with a small fee, since it taps directly into the protocol reserves rather than relying on AMM liquidity. Users who hold DAI can upgrade 1 to 1 into USDS using the official upgrade contract at sky.money.

Acquiring SKY follows the same pattern, with major CEXes listing SKY and the deepest on chain pools on Uniswap and Curve. MKR holders can upgrade to SKY at the fixed 1 to 24,000 ratio using the official upgrade contract, which is the cleanest path if you already hold MKR. The upgrade is reversible, meaning you can convert SKY back to MKR if you change your mind, though the conversion is one way per direction within a single transaction and incurs ordinary gas costs.

Once you hold USDS, the primary destinations are the Sky Savings Rate at sky.money for native yield, Spark Protocol for lending and borrowing exposure to the Sky ecosystem, and any major DEX for swapping or providing liquidity. The DEXTools complete guide covers how to track USDS trading activity and discover new pools as they launch. Holding SKY makes you a governance participant in the protocol, and the Sky governance forum and on chain voting interfaces let you weigh in on collateral parameters, savings rate, and SubDAO funding. For ERC20 mechanics applicable to both tokens, the ERC20 token standard guide covers approvals, allowances, and standard wallet flows.

Frequently Asked Questions

Closing Thoughts on Sky Protocol in 2026

Sky Protocol is the most ambitious restructuring any major DeFi protocol has attempted, and the early returns suggest the bet is paying off. USDS supply has grown faster than skeptics expected, the Sky Savings Rate has become a benchmark yield product across DeFi, and the SubDAO Stars are gradually showing how a single protocol can scale into many verticals without breaking governance. The freezability switch on USDS remains the most controversial design choice, but it has not been activated and the optionality has not yet caused observable user flight from USDS to DAI.

For everyday users in 2026, holding USDS in the Sky Savings Rate is one of the most efficient ways to earn dollar denominated yield in DeFi without exposure to a centralized issuer. For sophisticated users, opening vaults to mint USDS against ETH or wstETH collateral remains one of the cleanest ways to take leverage on Ethereum. For governance participants, SKY ownership gives a voice in one of the most consequential protocols in the space and a claim on its growing revenue. Whether you are migrating from MKR and DAI, evaluating USDS as a treasury asset, or just trying to understand how decentralized stablecoins evolved, Sky in 2026 is the most relevant case study in the space.

The protocol remains one of the load bearing pieces of DeFi infrastructure nine years after the launch of single collateral DAI. The brand has changed and the token economy has been restructured, but the core mission of providing a decentralized dollar that the rest of the ecosystem can rely on has stayed constant. Time spent understanding Sky is time well spent understanding DeFi itself.
